Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

(3,4,6,5)(7,8,9,10)(11,12)(13,16)(14,18)(15,17)(19,20,24,23)(21,26,22,25);(7,8,9,10)(11,13)(12,16)(14,15)(17,18)(20,23)(21,22);(4,5)(7,8)(9,10)(13,14)(16,18)(19,21,24,22)(20,25,23,26);(3,4,6,5)(7,8)(9,10)(11,14,15,13)(12,16,17,18)(19,22,24,21)(20,25,23,26);(1,2);(3,5,6,4)(11,12)(13,18)(14,16)(15,17)(19,23,24,20)(21,26,22,25)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((3,4,6,5)(7,8,9,10)(11,12)(13,16)(14,18)(15,17)(19,20,24,23)(21,26,22,25), (7,8,9,10)(11,13)(12,16)(14,15)(17,18)(20,23)(21,22), (4,5)(7,8)(9,10)(13,14)(16,18)(19,21,24,22)(20,25,23,26), (3,4,6,5)(7,8)(9,10)(11,14,15,13)(12,16,17,18)(19,22,24,21)(20,25,23,26), (1,2), (3,5,6,4)(11,12)(13,18)(14,16)(15,17)(19,23,24,20)(21,26,22,25));
